Well last night I rebooted and tried to run mcaffee, but it couldn't open. it said somthing about a .dll is missing or corrupt. rebooted a few more times, its running slow now and freezes occaisionaly. I ran spybot and it found 124 things, 2 said Klez worm.

hit the fix button but not all could be deleted inluding 1 Klez worm.

rebooted again and spy bot ran on bootup, but I wasn't sure if it got rid of the rest.
read up on this klez thing, theres a removal tool but I'll need to fix the .dll right? Will reformating wipe it out? I've heard horror stories were reformatting, and its still there don't know if they're true. I've been thinking of reformatting anyhow and cleaning this thing up but the wife needs some convincing. and its her computer.
